“The 1900-square-foot house on a ¼ acre close to Tilden Park, which hadn’t been touched since its original construction in the early 1970s, needed considerable updating! There is old growth redwood wainscoting throughout. It was beautiful but very dark and claustrophobic. Enter William Haynes, who through placement of larger windows, careful lowering of the wainscoting, removal of some unnecessary walls, and lowering counters built for a very tall previous owner, the house suddenly began to glow.

Along with windows and wainscoting, William remodeled and updated the kitchen and both bathrooms. The attention to detail and evident love of working with wood was a joy to see. William is so easy to work with; a true craftsman and a professional businessman. He gave honest and accurate estimates for his portion of the renovation. He not only brought the job in on time, but under budget!”
